Marath No Staples

This is from a series of decks where I take a completely overplayed general, look at the EDHREC page for it (in this case, this one), then not allow myself to play *any* card that appears on that page.
I ended up with a slightly weird Marath build that tries to make as large of a X/X token as possible, or uses the add +1/+1 counters ability.
This deck was made a couple of months ago (as of this writing), so there may be a few cards that shifted on to EDHREC's list. When I get around to updating this I'll double-check the list and adjust.
